Leviticus 21:15

¹⁶If the first fruit is holy, so is the lump. If the root is holy, so are the branches.

¹⁴For the unbelieving husband is sanctified in the wife, and the unbelieving wife is sanctified in the husband. Otherwise your children would be unclean, but now they are holy.

⁸Therefore you shall sanctify him, for he offers the bread of your God. He shall be holy to you, for I the LORD, who sanctify you, am holy.

¹⁵Did he not make you one, although he had the residue of the Spirit? Why one? He sought godly offspring. Therefore take heed to your spirit, and let no one deal treacherously against the wife of his youth.

⁶²These sought their place among those who were registered by genealogy, but they were not found; therefore they were deemed disqualified and removed from the priesthood.

¹¹Judah has dealt treacherously, and an abomination is committed in Israel and in Jerusalem; for Judah has profaned the holiness of the LORD which he loves, and has married the daughter of a foreign god.

²³In those days I also saw the Jews who had married women of Ashdod, of Ammon, and of Moab; ²⁴and their children spoke half in the speech of Ashdod, and could not speak in the Jews’ language, but according to the language of each people. ²⁵I contended with them, cursed them, struck certain of them, plucked off their hair, and made them swear by God, “You shall not give your daughters to their sons, nor take their daughters for your sons, or for yourselves. ²⁶Didn’t Solomon king of Israel sin by these things? Yet among many nations there was no king like him, and he was loved by his God, and God made him king over all Israel. Nevertheless foreign women caused even him to sin. ²⁷Shall we then listen to you to do all this great evil, to trespass against our God in marrying foreign women?”

²⁸One of the sons of Joiada, the son of Eliashib the high priest, was son-in-law to Sanballat the Horonite; therefore I chased him from me. ²⁹Remember them, my God, because they have defiled the priesthood and the covenant of the priesthood and of the Levites.

¹⁹For I have known him, to the end that he may command his children and his household after him, that they may keep the way of the LORD, to do righteousness and justice; to the end that the LORD may bring on Abraham that which he has spoken of him.”

²For they have taken of their daughters for themselves and for their sons, so that the holy offspring have mixed themselves with the peoples of the lands. Yes, the hand of the princes and rulers has been chief in this trespass.”
